What could be causing this?

Got an eyebrow piercing 3mo ago, and 1.5mo ago I hit my eyebrow pretty hard. It’s been red like this since then, and while my grandma (a nurse) says it’s not infected whatsoever she’s uncertain if it’s just a piercing bump or a hematoma. Any research I’m doing isn’t helping me at all with discovering which it could be. Should I change my jewelry? Take it out for a bit then put it back in? I’ve never gotten a facial piercing until this one.
